strip 22. The strip 22 has a reversely bent upper portion 23 which clamps about the horizontal flange of the weather strip, and has a base portion 24 which is so shaped as to fit tightly within the groove 25 in the top rail of the sash. This construction renders the weather strip resiliently yieldable, not only in part, but as a unit.

I claim 1. A top rail weather strip consisting of a strip of spring metal having one portion which is adapted to be connected to the top rail of a sash and another portion which is resiliently yieldable with respect to said con- 1 necting portion andis adapted to engage with the header of the sash frame, a flexible covering of compressible material on one face of said engaging portion of the strip, and another-flexible coveringon the opposite face go of said engaging portlon connected with the first mentioned covering for holding the same in proper position with respect to the strip.

2. A top rail weather strip consisting of a channel stri of spring metal having one por- 85 tion which is adapted to be attached to the top rail of a sash and another portion which is resiliently yieldable with respect to said attaching ortion and is adapted to engage with the hea er of the sash frame, a flexi l e covering of pile fabric on one face of said engaging portion of the strip, and another flexible covering ofpantasote on the op osite face of: said engaging portion attach to the edge strip of spring metal,- which strip is characterized by a lower attaching portion and an upper sealing portion, a connection between the lower portion of the strip and the top rail of the sash, a flexible covering of sealing material positioned in front of the upper portion of the strip, a connection between the lower portion ofthe covering and the lower portion of the strip, and means connected with the upper portion of the coveringfor maintaining the latter in proper relation to the upper portion of the strip. In testimony whereof I have hereunto sub scribed my name.
